REACTOR SELECTION AND DESIGN FOR COAL-DIRECT CHEMICAL LOOPING COMBUSTION PRODUCTION OF HYDROGEN
Chemical looping (CL) is reported as a promising technology for fossil fuel combustion because of its ability to produce a more concentrated carbon dioxide stream.This paper uses computational models to investigate the production of H2 via the Coal-Direct CL (CDCL) process using Victorian brown coal and an iron oxide as the oxygen carrier.The coal is gasified in-situ with the metal oxide, after which it is re-oxidised with steam and air.A concentrated H2 stream is produced from the oxidation with steam.Two different types of reactor configurations are examined, both consisting of a fuel reactor, air reactor and steam reactor, being a series and a parallel arrangement of the three reactors.Plant designs for 1 tpd (metric tonne per day) H2 production capacity were evaluated using a one-dimensional pressure balance model and ASPEN Plus(R).The designs were compared in terms of operating pressure, engineering design and operability, steam, water and energy requirements.
